I've been v. unhappy w/ UPS last few times I've used them. They're great at the delivery end, but more expensive and less ease on the quoting/packing end.

I haven't tried it with bike yet, but I've been very impressed with FedEx ground service. Did a lot w/ them couple years back for a temporary move.

Maybe too slow for your purposes if riding on the weekend, but they've been FABULOUS from talking on the phone, easy internet quoting and especially service on both ends. Shockingly fast for big boxes o' household stuff, way cheaper than UPS, and very well handled. Next time I ship bike or related stuff I'm checking with them first.
